The DNR’s geographic services develop maps ranging from locations of known confinement feeding operations to vulnerability to pollution from surface contaminants. Maps can also be used to locate well drilling logs, counties requiring the master matrix for construction permits or watersheds that have impaired waters. Other maps can provide insight into conservation or watershed planning, as well as information on everything from manure spills to alluvial soils. Check out the sites below for information specific to animal feeding operations. Then try Mapping (GIS Interactive) and Geology on the DNR homepage for everything from 2002 color infrared aerial photography to topographic maps.

The AFO Siting Atlas can be used to determine if a potential building or expansion location is in karst terrain or alluvial soils, or near a major water source. Instructions for using the site are available.

This site has interactive maps that provide a way to readily obtain information and Geographic Information Systems (GIS) data without having specialized GIS software. Map coverages include the 2002 color infrared air photography, soil erodibility, corn suitability ratings, land cover, etc.

This site requires the use of GIS software and is for downloading data files from the GIS library on the web. Its purpose is to allow GIS users to download data files and save them to a location on their computer. Then the file can be opened using ArcView. The files do not open directly from the site.
